When two gases interact with each other, they can exchange energy through various processes such as collisions and heat transfer.
In this case, we have two monatomic gases, A and B, that interact with each other. Gas A has 2.1 moles and an initial thermal energy of 4500 J, while gas B has 2.6 moles and an initial thermal energy of 8100 J.
During their interaction, the gases can exchange thermal energy through collisions. If the gases are in contact, they can exchange energy through conduction. If they are separated by a barrier, they can exchange energy through radiation. The specific mechanism of energy exchange depends on the conditions of the system.
Without knowing the specific conditions of the system, it is difficult to determine the exact outcome of the interaction between gas A and gas B. However, some general observations can be made based on the initial conditions of the gases.
Since gas B has a higher initial thermal energy than gas A, it is likely that energy will flow from gas B to gas A. This could lead to an increase in the thermal energy of gas A and a decrease in the thermal energy of gas B.
However, the exact amount of energy exchange depends on the specific conditions of the system, such as the temperature and pressure of the gases, and the nature of their interaction.
In summary, when two gases interact, they can exchange energy through various processes such as collisions and heat transfer. The specific outcome of the interaction depends on the conditions of the system, but in general, energy will tend to flow from the gas with higher thermal energy to the gas with lower thermal energy.

calculate the volume occupied by 10g of propane gas, under normal conditions of temperature and pressure
Answer:
5.5 L
Explanation:
First we convert 10 g of propane gas (C₃H₈) to moles, using its molar mass:
10 g ÷ 44 g/mol = 0.23 molThen we use the PV=nRT formula, where:
P = 1 atm & T = 293 K (This are normal conditions of T and P)n = 0.23 molR = 0.082 atm·L·mol⁻¹·K⁻¹V = ?1 atm * V = 0.23 mol * 0.082 atm·L·mol⁻¹·K⁻¹ * 293 K
V = 5.5 LN2 + 3H2 → 2NH3 How many grams of hydrogen are necessary to react completely with 853.42g of nitrogen in the above reaction?
Answer: 182.87 grams of hydrogen are necessary to react completely with 853.42g of nitrogen.
Explanation:
The balanced chemical reaction is :
[tex]N_2+3H_2\rightarrow 2NH_3[/tex]
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}[/tex]
[tex]\text{Number of moles of nitrogen}=\frac{853.42g}{28g/mol}=30.479moles[/tex]
According to stoichiometry:
1 mole of [tex]N_2[/tex] react with = 3 moles of [tex]H_2[/tex]
30.479 moles of [tex]N_2[/tex] will react with=[tex]\frac{3}{1}\times 30.479=91.437moles[/tex] of [tex]H_2[/tex]
Mass of [tex]H_2[/tex] =[tex]moles\times {\text {Molar mass}}=91.437mol\times 2g/mol=182.87g[/tex]
Thus 182.87 grams of hydrogen are necessary to react completely with 853.42g of nitrogen.
A gas has a volume of 500cm3 when a pressure of 100,00N is exacted on it what will be it's volume if the pressure is changed to 150mm mecury at same temperature
Answer:
See explanation below
Explanation:
At first sight, it seems that the innitial pressure of 100,00 N would be 100,00 N/m² because pressure does not have units of newton alone. If this is true, then the calculations are the following (If it's not, but it's actually mm Hg, then skip the part of the conversion, and just do the procedure of solving for the volume).
The innitial pressure is 100 N/m² or simply 100 Pa. As the second pressure is in mm Hg, let's convert the Pascal units to mm Hg:
1 Pa -----> 0.007501 mm Hg
100 ---------> X
X = 100 * 0.007501 / 1 = 0.7501 mmHg
Now that we have the innitial pressure in mm Hg, and the temperature remains constant, we use the Boyle's law to solve for this:
P₁V₁ = P₂V₂
V₂ = P₁V₁ / P₂
Using this expression, let's solve for V₂:
V₂ = 0.7501 *¨500 / 150
V₂ = 2.5 cm³
Now, it's the innitial pressure is 100 mm Hg then the volume:
V₂ = 100 * 500 / 150
V₂ = 333.33 cm³
Check the units of the innitial pressure, one of these results should be the correct answer. If it's not, then please post again the question with the correct units.

A scientist is comparing 2 samples of the same compound. One is pure and the other is impure. The compound is a solid at room temperature. Explain how the scientist could tell which is the pure compound. [2]
Answer:
A glass of mineral water is not pure water.
Explanation:
Pure chemical substances
Pouring water into a glass from a bottle
Food and drink may be advertised as ‘pure’. For example, you may see cartons of ‘pure orange juice’ or ‘pure mineral water’. This means that nothing else was added to the orange juice or mineral water during manufacture. However, these substances are not pure to a scientist. In science, a pure substance contains only one element or compound.
Mineral water is mostly water, but there are other substances mixed with it. These are the ingredients that you see listed on the bottle’s label.

how many atoms are in each compound ?
how many atoms of alumminum are in 3.9 mol of aluminum
Answer:
2.35 x 10²⁴ atoms Al
Explanation:
Given 3.9 moles of aluminum (Al), determine number of aluminum atoms in that quantity of substance.
By definition a mole is the mass of substance containing one Avogadro's Number (N₀) of particles. That is, 1 mole = 1 N₀ = 6.023 x 10²³ particles*.
So, if 1 mole aluminum contains 6.023 x 10²³ atoms of aluminum then
3.9 moles Al = 3.9 moles Al x 6.023 x 10²³ atoms Al/mole Al = 2.35 x 10²⁴ atoms Al.
________________
*The complete equivalent relationship is ...
1 mole (atoms or compounds) = 6.023 x 10²³ atoms or molecules = 1 formula weight of the substance = 22.4 Liters (if in gas phase at STP conditions (0°C and 1atm pressure).
________________
Sure hope this is understandable ... if not, kick back a note. Doc

if you need 2.5 moles of of aluminum, how many atoms of aluminum is this?
Answer:
This can be found by my multiplying number of moles with avogadro number
So we have:
2.5 × 6.022 × 10²³
= 15.055 × 10²³
Therefore there are 15.055 × 10²³ atoms in 2.5 moles of Aluminium

The transfer of ____________ is achieved when eating and feeding exists
Answer:
the transfer of energy because eating is gaining energy from a source, so the energy from that source is being transfer to the animal.
The transfer of energy is achieved when eating and feeding exists. Chemical processes may emit or absorb chemical energy.
What is energy?The ability of a physical process to carry out work is known as energy. It's crucial to remember that simply because energy exists doesn't indicate that it is always ready to do tasks. Thermal energy, sometimes known as heat, is generated when atoms or molecules move. It may be thought of as temperature-related energy.
This energy results from the location of an item. For instance, a ball resting on a table possesses potential energy in relation to the ground because of the influence of gravity. Chemical processes may emit or absorb chemical energy. It is created by atoms and molecules establishing or breaking chemical bonds.
Therefore, the transfer energy is achieved when eating and feeding exists.

Are physical characteristics of an organism not genetically passed down?
In an ecosystem, the physical characteristics of an organism are genetically passed down from one generation to another.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.
